Allow the time slider to be enabled while editing. For example, I have a polygon that was created in 1942, and modified in 1980 by having an area clipped out. I want the end date for the original polygon to be 3/25/1980, which will be the start date for the new polygon. The new polygon will start as a copy of the original, and then I want to edit just the polygon that started on 3/25/1980, preferably by changing the time to anytime the new polygon exists. This way I don't have to worry about clipping the original polygon because it doesn't exist in that time.
This idea has been merged with Enable Time Slider During Edit Session.
